8.2.Middle English Period

At the beginning of the Middle English period, which dates from the Norman Conquest of 1066, the language was still inflectional; at the end of the period the relationship between the elements of the sentence depended basically on word order. As early as 1200 the three or four grammatical case forms of nouns in the singular had been reduced to two, and to denote the plural the noun ending -es had been adopted.

The declension of the noun was simplified further by dropping the final n from five cases of the fourth, or weak, declension; by neutralizing all vowel endings to e (sounded like the a in Modern English sofa), and by extending the masculine, nominative, and accusative plural ending -as, later neutralized also to -es, to other declensions and other cases. Only one example of a weak plural ending, oxen, survives in Modern English; kine and brethren are later formations. Several representatives of the Old English modification of the root vowel in the plural, such as man, men, and foot, feet, also survive.

With the levelling of inflections, the distinctions of grammatical gender in English were replaced by those of natural gender. During this period the dual number fell into disuse, and the dative and accusative of pronouns were reduced to a common form. Furthermore, the Scandinavian they, them were substituted for the original hie, hem of the third person plural, and who, which, and that acquired their present relative functions. The conjugation of verbs was simplified by the omission of endings and by the use of a common form for the singular and plural of the past tense of strong verbs.

In the early period of Middle English, a number of utilitarian words, such as egg, sky, sister, window, and get, came into the language from Old Norse. The Normans brought other additions to the vocabulary. Before 1250 about 900 new words had appeared in English, mainly words, such as baron, noble, and feast, that the Anglo-Saxon lower classes required in their dealings with the Norman-French nobility. Eventually the Norman nobility and clergy, although they had learned English, introduced from the French words pertaining to the government, the church, the army, and the fashions of the court, in addition to others proper to the arts, scholarship, and medicine. Another effect of the Norman Conquest was the use of Carolingian script and a change in spelling. Norman scribes write Old English y as u and u as ou. Cw was changed to qu, hw to wh, and ht to ght. Midland, the dialect of Middle English derived from the Mercian dialect of Old English, became important during the 14th century, when the counties in which it was spoken developed into centres of university, economic, and courtly life. East Midland, one of the subdivisions of Midland, had by that time become the speech of the entire metropolitan area of the capital, London, and probably had spread south of the Thames River into Kent and Surrey. The influence of East Midland was strengthened by its use in the government offices of London, by its literary dissemination in the works of the 14th-century poets Geoffrey Chaucer, John Gower, and John Lydgate, and ultimately by its adoption for printed works by William Caxton. These and other circumstances gradually contributed to the direct development of the East Midland dialect into the Modern English language. During the period of this linguistic transformation the other Middle English dialects continued to exist, and dialects descending from them are still spoken in the 20th century. Lowland Scottish, for example, is a development of the Northern dialect.
